Question

The time for which the data is to be on the BUS is affected by __________

(a) Propagation delay of the circuit

(b) Setup time of the device

(c) Memory access time

(d) Propagation delay of the circuit & Setup time of the device

The question was posed to me in an interview for internship.

This interesting question is from Synchronous BUS in portion Input/Output Organisation of Computer Architecture

Answer 1

The correct option is (d) Propagation delay of the circuit & Setup time of the device

For explanation: The time for which the data is held is larger than the time taken for propagation delay and setup time.
